audio device not connected

ProBook 4720 s energystar

It is a problem of repetition. Last year it was resolved after I downloaded a driver who has been recommended by the Committee. He worked for a while then come back to this message. Unfortunately, I don't remember downloading this driver. So, my problem is when I plug my ProBook on TV, I get no sound french the HDMI cable. When I check my output device, I noticed that AMD-output HDMI is not plugged.

Please help because I like to show things on television.

Thank you in advance, Caspar

I'm sorry, but to get your question more exposure I suggest posting in the trade forums since it is a commercial product. You can do http://h30499.www3.hp.com/hpeb/

    original title: no sound coming from my speakers

    To everyone

    Thanks for trying to help me.  However, since some of the suggestions seem to me be beyond my capabilities, I decided to take the hard drive to a computer technician.

    It took him an hour to solve the problem.  One of the problems was that the new map, he installed had crushed WMV. He is also turned off user account control.

    Everything works now and I'm very happy, because I had spent the day trying to solve the problem.

    Once again, thank you to all of you who gave me your opinion.

  • HP C4780 and Airport Extreme: says "device not connected" when installing wireless

    Hello.  I appreciate any help with this problem.  I searched but I've not found anything exactly similar.  I have a MacBook Pro under OSX 10.5.8 and an Airport Extreme.  I am trying to set up a HP C4780 printer using the HP installation software.  The printer is connected to the Mac via a USB cable for Setup, and all the steps of the Setup routine recognized the printer.  Until... when I get to the part "network wireless configuration" of the process, Setup HP sees my network (802.11n, the type of encryption WPA_PSK) and asks for my password.  After I entered the pw, it runs for about 20 seconds and gives me the following message: "device not connected.  To configure the network settings for the device selected, please temporarily connect via USB. The device can be disconnected from the USB once the network settings are transferred. »

    My printer is well connected by USB, however.  By reading some similar positions, I tried the following: limit the wireless to channell 11, by clicking on the button "allow this network be extended" and disconnect the printer before the launch of wireless setup.  I also tried several bottles of beer, but which only degrades the connection between the keyboard and the seat.  No luck so far.  Any help would be appreciated.  Thank you.

    C4700 series has a bug in the firmware where it crashes when meeting a SSID of 6 characters.

    Change your SSID to 10 or 12 characters until a firmware fix is published.

    If this does not work, drink more beer.

  • audio device not supported Mac 6.1

    I just spent some time on telephone support to adobe tent to solve a problem, but only had a half fix.  I get an error of an audio device not supported on my Mac 6.1.  Nothing would in return play, I tried several fixes online, switching equipment, etc., but he was always pushing an error in audio device not supported (using audio devices in the Mac).  The problem was bypassed, then when we were able to create a global audio device that uses a webcam logitech for a microphone input and audio built-in for output.  Now I was getting sound and the guy said that the problem has been completely resolved and I'm good to go.  So I start to play my audio to the rear, and while it does not play back audio, he locked not able to go up to 44.1 Khz or 48 kHz 16 kHz.  Once I tried to remove the logitech camera is a no go once again.

    Everyone knows about this problem with the latest OSx and CC2015 Premiere Pro?  Is there a solution?  Also, we went in the Library preferences and renamed the 9.0 folder so that it created a new file, preferably without success on PR. (although it has fixed hearing).

    Tried with bars and tone as well as with images.

    Thanks in advance!

    To be more precise, it gave the following error:

    "The device settings could not be applied because the following error occurred:

    The sampling frequency is not supported by the current audio device.

    The last valid device settings will be used.

    SOLUTION

    I just removed my Logitech camera on the computer, and all of a sudden, it works like a charm...  Clogged again and it wouldn't work... unplugged it and it worked again. It seems that if no input is available, output cannot exceed the rate of sample entries (perhaps because of the recording VO feature?  Whatever it is, that fixed it.  If anyone has this problem before they fix it, I hope this will help them.

    The audio on my laptop stop working. I tried to do troubleshooting, still no results. When I try to adjust the volume, it says no audio device connected, but there are built-in speakers. What can I do to fix this?

    You could try visiting support site for this specific model of laptop on the manufacturer's website and download the latest audio driversavailable, and then install them. Who can decipher Windows problem with audio and make it work again.

    Also, wouldn't hurt to search for malware with a tool such as Microsoft Security Essentials , Malwarebytes , or SpyBot in case some malware is active on your system and interfere with it in a way that has disabled the audio.

    I'm a form of error message 'no audio device detected' each time than trying to use a program with sound.  ITunes, for example, says "Itunes has detected a problem with your sound configuration."  No sound works on the computer at all.  I have a dell Inspiron E1505 with I think it's the integrated audio system.  I tried to reinstall the drivers and that sound showcases are activated and similar these fixes.  Another oddity: sometimes my laptop speakers do weird sounds like it is a kind of bad connection inside, but I opened the computer to check and nothing seems to be wrong.  In addition, once a week ago, I turned on the computer and everything works fine until I closed the computer and opened again to find nothing works again.  Ideas?
